<h3 id="why-keep-your-iredmail-server-up-to-date">Why keep your iRedMail server up to date</h3>
<ul>
<li>The latest iRedMail release brings new features, improvements, and bug fixes.</li>
<li>If you plan to migrate to a new iRedMail server someday, migrating iRedMail
  to another server which runs the same release is the easiest path.</li>
</ul>
<h3 id="how-upgrading-works">How upgrading works</h3>
<ul>
<li>
<p>Usually, upgrading iRedMail is just updating some config files to achieve new
  features or fix bugs, you do <strong>NOT</strong> need to download and run the latest
  iRedMail installer (<code>bash iRedMail.sh</code>).</p>
</li>
<li>
<p><strong>Do NOT skip releases</strong>. Upgrades are only supported from one release to the
  release immediately following it.</p>
</li>
<li>
<p>If you're looking for upgrading a very old iRedMail server to the latest
  iRedMail release, there's an alternative solution:
